Carbonate

The carbonate ion is a polyatomic anion with the empirical formula CO32- and a molecular mass of 60.01 daltons; it consists of one central carbon atom surrounded by three identical oxygen atoms in a trigonal planar arrangement. The carbonate ion carries a negative two formal charge and is the conjugate base of the hydrogen carbonate ion, HCO3-, which is the conjugate base of H2CO3, carbonic acid.
